The problem I had was in the GRUB_CMDLINE_LINUX line in the /etc/default/grub file. The first rd.md.uuid was supposed to be the uuid for the Linux RAID member disks that make up the mdraid devices from which you want to boot.
The second rd.md.uuid that pointed to the RAID member disks used for the root filesystems and LVM was missing!
Yes, I figured it'd be something like that once I realized there really were two mdraid arrays, but only one rd.md.uuid parameter. What's curious is that its absence wasn't causing a problem before the upgrade.
Correcting both rd.md.uuid entries to reflect the correct devices in that file and running dracut -f before rebooting resolved my problem.
Well in the end that's all that matters.
